U.S. Special Counsel Robert Mueller on Friday submitted a list of 35 potential witnesses for the trial of President Donald Trump's former campaign chairman Paul Manafort due to begin next week in Virginia, including bankers and accountants likely to testify regarding charges of bank and tax fraud.

The list, disclosed in a court filing, included Manafort's longtime business associate Richard Gates, who was indicted in October at the same time as Manafort, pleaded guilty in February and has been cooperating in Mueller's probe.

Also on the list was Tad Devine, a consultant who worked with Manafort in Ukraine and served as chief strategist for 2016 Democratic presidential contender Bernie Sanders. Devine's firm said in a statement he was serving as a fact witness and had been assured he did not have legal exposure.
